I eat and like haggis. While many do eat haggis few actually enjoy it. Haggis is a dish containing sheep's 'pluck' (heart, liver and lungs), minced with onion, oatmeal, suet, spices, and salt, mixed with stock, and traditionally simmered in the animal's stomach for approximately three hours.

Gelatin making is a lot cleaner than folk would have you believe. A vat of lime is 'dead' and near sudden death for rats and insects. Some bacteria may thrive in lime, but if they thrive in lime they most likely will not do well in a 'normal' environment.

Liming hide and other things to render out its usefulness has been in practice for generations. Think Gelatin is bad, wait until you find out the process by which leather is tanned.

Back on the farm we rendered fat for tallow, and also made our own lye by the egg method from whence came our soap. We also boiled down hides for gelatin, and we also "gathered" together our own rennet for cheese making. [link to www.ask.com] We also tanned the hides, not just the occasional cow we slaughtered at home, but the smaller critters like rabbit, squirrel, deer, opossum and even a few raccoons. Oh and be the way we also ate the meat from those critters that we hunted as well.

If you are grossed out about Jello, which is far cleaner when it is packaged being sterilized via heat in the process, then please don't bother eating eggs (these are often covered in chicken poo), don't bother eating meat after all the things that we feed to the animal plus the wonderful life they spend on a stinking, rat infested, insect infested farm, or for that matter do not find out about how much bug parts are allowed in the processing of Peanut butter.
